Decidueye and friends deck

[Honeydew Haiku]

So I used to play in TCG tournaments, and I'm thinking about getting back into it. Lately I've been playing PTCGO and collecting some cards. I finally decided to put together an ideal deck that I might be able to purchase and play in real life... I have maybe some idea of what I'm doing, but I'm a little behind on the times still. Anyway... tl;dr: critique my deck please? :)
